Embodiment
Original application
Fig. 1 has shown and has been used for from gas-liquid flow 32 coalescently and remove the inertial gas-liquid impingement separator 30 of the little drop of liquid that it is to ventilate to separating in the typical crankcase of internal-combustion engine 34 to using.In such application, it is desirable for and from the crankcase 36 of motor 34, discharge blowby (blow-by) gas.Under undressed situation, these gases have comprised the particulate material that is mist of oil and oil smoke form.What wish is the concentration of control pollutant, if particularly blow-by gas is recycled back into the gas handling system of motor, for example at intake manifold 38 places.The diameter of the droplet of mist of oil is usually less than 5 μ, and when therefore keeping low flow resistance in filter medium collection and oiliness and pollutant, it is difficult using the traditional fibre filter medium to remove.
The given parameter change of variable flow actuator 62 responses the stream of accumulating by a plurality of nozzles.In a desirable embodiment,, change here and accumulate flow velocity (cumulative flow velocity) though other flow characteristics can be changed.Gas-liquid flow is along crossing spout 50,52 in the axial flow direction axial flow at 58 places.Regulator 62 can move with respect to described spout along assigned direction, to change the described stream of accumulating.In one embodiment, regulator 62 is removable with respect to nozzle along assigned direction, to change the gross area, therefore changes total flow velocity.In Fig. 1,2, regulator 62 is dishes or dull and stereotyped, and it is removable to pass one or more spouts, so that change its cross sectional area perpendicular to axial flow direction 58.Dish 62 can be shown in arrow 64 among Fig. 1,2, and the horizontal left and right directions of axial flow direction 58 moves.In Fig. 1,2 embodiment, dish 62 has a plurality of elongated slots or opening 66,68, and it aligns with spout 50,52 respectively and can laterally slide along it, so that change the size that axial flow kinetic energy passes through, thereby change the area of accumulating stream.In another embodiment, in the process of dish 62 motions, can close or open one or more spout 50,52, change the number that the spout of axial flow therefrom can be arranged like this, therefore change the described area of accumulating stream.In another embodiment, the motion of regulator dish 62 all changes the size and the number of spout, for example regulator dish 62 can enlarge and restrictive orifice along its cross sectional area perpendicular to flow direction 58 along the to-and-fro motion of direction 64, to change the size of spout, regulator dish 62 can open and close other spouts along direction 64 to-and-fro motion, so that the number of the spout that the change gas-liquid flow flows through.
In one embodiment, the described parameter of variable flow actuator 62 responses is the pressure of gas-liquid flow.Housing 40 comprises pressure transducer 70, and this sensor has diaphragm or form of film, is connected to regulator 62 by link 72, so that regulate regulator 62, makes it move left and right shown among Fig. 1,2 64.When the pressure of gas-liquid flow increased, diaphragm 70 was moved to the left in Fig. 1, and the number that this has increased the size (having increased the cross-sectional flow area of spout) of spout 50,52 etc. with preferred form and/or has increased the spout 50,52 opened etc. is therefrom flowing.Pressure in the increase of the gas-liquid flow of 74 li of housing cavity has overcome biasing spring 76, caused diaphragm 70 to left movement.If gas-liquid flow pressure descends, the biasing spring 76 regulator dish 62 that moves right in Fig. 1 has so preferably reduced the size and/or the number of spout 50,52 etc.By this way, kept the pressure difference Δ P that wishes, and need not take halfway measures in minimum and Peak Flow Rate, size of engine, changing condition, described changing condition is engine scuffing, speed, braking etc. for example.By being adjusted in different size of engine, flow velocity and the changing condition in the engine operation, variable flow actuator makes efficient reach maximum, has overcome the existing shortcoming (trade-offs) of taking into account that needs in the fixed flow separator.In the embodiment in figure 1, be communicated to atmosphere at discharge aperture 80,82 places with respect to reference Δ P with housing cavity 78 on the opposite side of chamber 74 relative diaphragms 70,, but other reference pressures can be used.
Fig. 3 has shown another embodiment, and this embodiment has that regulator is dull and stereotyped or coil 84, and it can slide along translations ground, housing 88 left and right sides shown in arrow 86, so that change along the size of the spout 90,92 of the slit groove of its dish that moves 84 or opening 94,96 grades.Groove or opening 94,96 can have truncated cone 98, so that strengthen described Venturi tube acceleration effect.When dish 84 when being moved to the left in Fig. 3, the size of Venturi tube spout 90,92 increases, that is, regulator dish 84 enlarged the size of spout 90,92 to left movement along the cross sectional area of its flow direction 58 perpendicular to axial direction, to change the size of spout.Regulator dish 84 motion has to the right limited spout 90,92 along the cross sectional area of its flow direction 58 perpendicular to axial direction.Alternatively, perhaps additional, regulator dish 84 can open other spout to left movement, and moving right of regulator dish 84 can be closed some spouts, so that change the number of the spout that wherein flows through gas-liquid flow.
Fig. 4 has shown another embodiment, and it has can be around the regulator dish 100 of running shaft 102 rotations that are parallel to axial flow direction 58.Regulator dish 100 can turn clockwise around axle 102 shown in arrow 104, limits and/or close one or more spout 106,108 of shell wall 110 etc. when spout is passed in groove 112, the 114 horizontal slips of 100 li on regulator dish with box lunch.
